Manufacturers typically look to universal drills to help
reduce the need to maintain large, diverse tools stocks. However, a
one-size-fits-all solution often cannot provide the tool life or cutting speeds
of tools optimized for a given application or material. To meet the needs of
manufacturers for whom performance and tool life are the most critical factors,
Seco developed the Feedmax™ -P, which incorporates geometric features optimized
for superior surface finishes and the highest productivity in iron and steel.
Designed to run at extreme speeds and feeds, the Feedmax™ -P
has large tapered flutes and straight cutting edges to ensure greater strength
and efficient heat dissipation. The precise location of the through-tool
coolant holes and the larger flutes quickly and efficiently evacuate chips, and
the need for pecking is eliminated when the machine maintains appropriate
coolant pressure. For this drill design, Seco engineers placed the through-tool
coolant holes as close as possible to the ideal position on the cutting edge.
With narrow land margins, the Feedmax™ -P reduces friction
and diminishes the wear of the connection between land margin and corner
chamfer to promote better chip formation and decreases heat generation. This
geometric feature also minimizes the risk of chipping, which gives the drill a
more predictable tool life and higher application security.
To further improve the performance of the Feedmax™ -P, Seco
Tools utilized a special double-layer TiAIN (titanium aluminum nitride) coating
to increase the drill’s oxidation resistance. A thick bottom layer promotes
heat dissipation while the top layer helps prevent built-up edge. In addition
to proper heat dissipation and good edge retention, this double-coating process
promotes excellent adhesion and eliminates flaking to promote long tool life.
Thanks
to its advanced TiAIN coating and strong point geometry, the Feedmax™ -P
makes cutting speeds
of 623 feet/min possible in SMG P5 without sacrificing tool life. But
to reap the full benefits of the Feedmax™ -P’s advanced holemaking
technologies, shops must set up the drill properly and run at the correct
speeds and feeds. When they do, the performance of the Feedmax™ -P amazes most
users. More impressive still, those basic parameter values are actually relatively
conservative based on the actual performance capability of the drills. By
following the recommendations, manufacturers can achieve highly effective chip
evacuation and enjoy the full value of their tool investment.
